Rabbit tail injury please help

Hello, I found this tail injury in one of my meat rabbits (New Zealands) today. He seems fine, eating as normal. The injury is hidden and can’t normally seen (since the tail is tucked up) so I don’t know how long he has been like this. I did inadvertently have another male rabbit with him in his crate overnight (which was a mistake); so not sure if that’s what caused this.

If it were my rabbit, I would douse it liberally with golden seal powder, failing that, at a pinch, turmeric powder could work.  Repeat until it has dried and do not disturb until a scab has formed and mother nature takes its course. However, I am sure more advice will come shortly and you can decide what will be best for you and your bunny.  Whatever, I hope it heals well and soon.  All the best

PS If you use the above method, be prepared to have a yellow tailed bunny for a while!

Hope your bunny is better.

It looks like the area is healing, I see fur growing back. Fingers crossed he recovers fully, and doesn’t happens again. I looked more into it and pretty sure it’s “urine scald”. I had left extra hay in his kennel while I was traveling, which ended up lining up the floor and getting soaked in his pee.
